“…, and 629 cm À1 , slightly shifted from the peaks identified by Robert and colleagues [37], most likely as a result of differences in NM particle size [35]. Major Raman peaks features at approximately 1,005 cm À1 , 1,155 cm À1 , and 1,525 cm À1 have also been highlighted in Figure 6c and are associated with carotenoids, typical pigments in algae.…”

“…The broad multiple peaks at ϳ239 cm −1 indicate the presence of amorphous contributions which correspond to a second order scattering process. 45 On the other hand, for the curve l the spectrum shows traces of the rutile phase and three of the six fundamental Raman active modes characteristic of anatase structures located at ϳ148 ͑E g ͒, ϳ401 ͑B 1g ͒, and 640 cm −1 ͑E g ͒. 45,46 Other expected modes, such as A 1g and B 1g , at ϳ518 cm −1 are masked by the signal of silicon substrate.…”

All spectra recorded with samples deposited with P O 2 Ͼ 9.95ϫ 10 −5 mbar are unambiguously compatible with anatase crystalline structures.…”

“…In this configuration, the average current density is equal to 330 mA cm -2 and an average discharge power (calculated with the method described in [14]) equal to 282 W. [15][16][17]. A small broad multiple peak at 230 cm -1 , especially conspicuous above 773 K, is due to a second order process in rutile vibrational modes [18]. We can moreover notice that the Raman intensity of graphitic carbon decreases significantly once the coating is submitted to a calcination process.…”
